We're dividing 363701 by 91 
The aim is to understand the frequency of 91 in 363701.

Let's proceed to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 91

Let's proceed to step 2:
When dividing 36 by 91, we get 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 91

Step 3:
91 goes into 363 3 times with a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 273 from 363 leaves us with 90.
Grab the next digit (7) from the dividend, add it to 90, then carry on: 907 / 91

Advancing to step 4:
907 divided by 91 is 9 with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 819 from 907 to get 88.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 91

On to step 5:
91 goes into 880 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 399.0
Subtracting 819 from 880 leaves us with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 91

Step 6:
611 divided by 91 is 6 with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 3996.0
If we subtract 546 from 611, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
The number 91 fits into 650 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 3996.7
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
If we divide 130 by 91, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 3996.71
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
390 divided by 91 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 3996.714
The remainder is 26 after subtracting 364 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
260 divided by 91 is 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 3996.7142
Subtracting 182 from 260 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 11:
91 can be fit into 780 8 times, resulting in a remainder of 52.
The next digit of our result is 8. 
Result so far: 3996.71428
If we subtract 728 from 780, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
91 can be fit into 520 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3996.714285
If we take 455 away from 520, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
650 divided by 91 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 3996.7142857
The remainder is 13 after subtracting 637 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
130 divided by 91 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 3996.71428571
Subtract 91 from 130 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 3996.71428571, and the remainder is 3.9e-08.
